No. M348858 comprises a driving device, a hydropower generator, and a recycle tank, and the driving device includes a delivery set having a storage cylinder, a pressure cylinder, a water inlet pipe and a water outlet pipe installed at the bottom of the cylinders, and a piston is installed and coupled to the top of the pressure cylinder and the storage cylinder, wherein the hydropower generator and the driving device are coupled to the water outlet pipe, and a water discharging pipe is installed on a side different from the water outlet pipe of the driving device, and the recycle tank, the water discharging pipe of the hydropower generator, and the water inlet pipe of the driving device are coupled to one another, so that a working fluid can be circulated and used repeatedly.

Although the aforementioned conventional hydropower equipment can circulate and use the working fluid repeatedly, the hydropower generator can generate power only when the piston compresses the working fluid downwardly, but no power is generated when the piston moves upwardly. As a result, the power generation performance of the conventional hydropower equipment is poor. Particularly, if the hydraulic cylinder drives the piston, and the piston pushes the working fluid to move, the speed of the moving working fluid is low, so that the electric power generated by the hydropower generator is limited significantly.

SUMMARY OF THE INVENTION

To achieve the aforementioned objective, the present invention provides a power device using a gas to drive a liquid, and the power device comprises a container, a specific quantity of liquid, a driving mechanism, a specific quantity of gas and a power generator, wherein the container includes a first chamber, a second chamber, and a communicating hole formed between the first chamber and the second chamber; the specific quantity of liquid is filled into the first chamber and the second chamber; the driving mechanism includes a moving object contained in the first chamber; the specific quantity of gas is filled into the first chamber and disposed between the moving object and a liquid surface of the specific quantity of liquid; the power generator is installed at a position corresponding to the communicating hole; wherein the moving object increases or decreases pressure during the process of moving the specific quantity of gas back and forth, so as to drive the specific quantity of liquid to flow into or out from the communicating hole to drive the power generator to generate power.

To achieve the aforementioned objective, the present invention provides a power device using a gas to drive a liquid, and the power device comprises a container, a specific quantity of liquid, a gas with a variable pressure and a power generator, wherein the container includes a first chamber, a second chamber, and a communicating hole formed between the first chamber and the second chamber; the specific quantity of liquid is filled into the first chamber and the second chamber; the gas with a variable pressure is filled into the first chamber and disposed at a liquid surface of the specific quantity of liquid; the power generator is installed at a position corresponding to the communicating hole; and the pressure of the gas can be increased or decreased to drive the specific quantity of liquid to flow out from or into the communicating hole to drive the power generator to generate power.

The density of the gas is much lower than the density of the liquid, such that the gas can be used to drive the liquid to move rather than using a liquid to drive another liquid to move, and the air pressure difference produced by the two chambers can be used to drive a certain volume of liquid, so that the power generator can generate a large quantity of electric power. The converging passage and the diverging passage formed on both sides of the impeller respectively and operated together with the check valve can rotate the impeller in the same direction to drive the power generator to generate electric power.

The hollow rectangular body includes a partition 12 installed at a central position inside the hollow rectangular body to divide the interior of the container 10 into a first chamber 13 and a second chamber 14, and a communicating hole 121 formed at the bottom of the partition 12 (as shown in FIG. 4), such that the first chamber 13 and the second chamber 14 are interconnected with each other through the communicating hole 121. A lining member 15 is installed at a position at an upper part of the first chamber 13, and a through hole 151 is formed at a central position of the lining member 15. In addition, a first drainage structure 16 is installed separately at lower corners of the first chamber 13 and the second chamber 14 respectively, and the first drainage structure 16 has an arc drainage surface 161.

The liquid 20 can be water or any liquid produced by mixing an anti-freeze agent, a lubricating agent or any other ingredient into water. The liquid 20 is filled into the first chamber 13 and the second chamber 14.

The driving mechanism of this preferred embodiment is a vertical driving mechanism 30 installed on the container 10. The driving mechanism 30 comprises an electric motor 31, a driving wheel 32, a link rod 33 and a moving object 34. The electric motor 31 is mounted onto the partition 12 by a rack. The driving wheel 32 is a circular disc whose center is sheathed on an axle of the electric motor 31. An end of the link rod 33 is pivotally coupled to a position with a certain distance from the center of the driving wheel 32. In this preferred embodiment, the moving object 34 is a piston which can be made of foam (such as polylon), carbon fiber, fiberglass or metal material, and the moving object 34 includes a circular disc 341 contained in the through hole 151 and a straight rod 342 fixed to the central position of an upper surface of the circular disc 341, and a free end of the straight rod 342 is pivotally coupled to another end of the link rod 33.

The gas 40 can be air filled into the first chamber 13 and situated between a front surface of the circular disc 341 of the moving object 34 and a liquid surface of the liquid 20.

The power generator 50 of this preferred embodiment is a turbine having a motor portion 51 and an impeller 52 coupled to the motor portion 51, and the power generator 50 is installed in the container 10, and the impeller 52 is installed at a position corresponding to the communicating hole 121.

With reference to FIGS. 4 and 6, the container 10 of the present invention further includes a second drainage structure 17 formed at the bottom of the plate 11 and at a position corresponding to the communicating hole 121. The second drainage structure 17 includes two drainage blocks 171, two check valves 172 and two diversion blocks 173, and each drainage block 171 is fixed on internal walls on both sides of the plate 11 separately, and each diversion block 173 is substantially in a triangular shape and separately installed in a pair on both corresponding sides of the impeller 52. An end of each check valve 172 is pivotally coupled onto a divergent surface 1711 of the drainage block 171, and another end of the check valve 172 is closed or opened intermittently along the flowing direction of the specific quantity of liquid 20. A converging passage 174 and a diverging passage 175 are formed between each drainage block 171 and each diversion block 173 respectively, and the converging passage 174 is formed on a side of the impeller 52 for flowing in the specific quantity of liquid 20, and the diverging passage 175 is formed on a side of the impeller 52 for flowing out the specific quantity of liquid 20, so that the impeller 52 is capable of rotating in the same direction, reducing the impact force when the specific quantity of liquid 20 flows through the impeller 52, and increasing the speed of flowing the specific quantity of liquid 20 through the impeller 52.
